    Hi Vasu,

    To make sure I understand correctly, are you referring to the Postman API development environment? I assume this is being used to test out the API for a service you are building and will have the device ultimately interact with.

    It looks like the device is running an application similar to the local_ota example, is that correct?

    Yes, you can send json data to the device through the HTTP server. The requirement for that type of encoding is only when utilizing the RESTful API processing in the device. Refer to section 8.4 of the Network Processor Programmer's Guide.

    Hi Benjamin Moore,

      I am using postman for testing purpose.

      testing purpose i modified local_ota_example.

      I can able to send json data using PUT/POST request that's also working fine.

      My problem is see postman request i am sending three certificate at same time certificate also received in callback function that's fine but how to find each file size ? 

        cert1 size = ?

        cert2 size = ?

        cert3 size = ?

    How to find each file size ?

    Thank You

    Hi Vasu,

    Thanks for the additional information. The local OTA example works by extracting an archive that contains all the files that are to be updated. The size of each will be determined while the archive is extracted rather than in the top-level callback where the data is first received.

    Are you having an issue with this? Or did you want to modify the process somehow?

    You could send each file separately and not as an archive if you want, then the length you are referring to would be correct for each individual file.

    Hi Benjamin Moore,

    Local ota there is no issue working fine.

    Sending file separately callback received file i already tested working fine.

    After that i am trying to send three file and some configuration but i can't find each file size .

    I try some other method to find file size.

    Thank you
    Vasu
